The TriLink Saw Chain features Centri-Lube oil-ways on all drive links. These oil-ways allow lubrication to flow up through the drive links and to the rivets. This reduces friction, chain stretch and results in fewer adjustments needed to the chain. This chain has hardened, chromed full-chisel cutters designed for excellent chip clearance for fast, smooth cutting at high-speeds in clean conditions, preferred by professional users.
